APPARATUS FOR PRESSING AND DRYING GARMENT-STAYS.

SPECIFICATION forming part of Letters Patent No. 571,992, dated November24, 1896.

Application filed February 26, 1896. Serial No. 580,767. (No model.)

Be it known that I, JOHN S. OROTTY, a citizen of the United States,residing in the city, county, and State of New York, have inventedcertain new and useful Improvements in Apparatus for Pressing and DryingStays, of which the following is a specification.

In the manufacture of corsets, stays, or ribbed or boned sections ofcorsets it is requisite to submit to heat and pressure the casings orfabrics containing the series of parallel blades cemented between saidcasings for the purpose of drying and'securing the blades in thefabrics; and my invention consists of means whereby this operation maybe efiected economically and rapidly without the loss of time incidentto the ordinary method of inserting the casings between the plates of apress as usual, and to this end I construct the press and the holder forthe casings as fully set forth hereinafter and as illustrated in theaccompanying drawings, in which Figure 1 is an elevation of the press.Fig. 2 is a perspective view illustrating the plates of the press andthe holders and showing how the same are manipulated, and Fig. 3 is asec tional view of one of the holders.

The press consists of a foundation A, to the corners of which aresuitably secured four uprights or standards 3, which extend to and areattached to the corners of the upper hollow plate B of the press. Uponthese standards 3, as guides, slides the lower hollow plate 0 of thepress, and steam is admitted to the chamber in each plate throughflexible pipes, (not shown,) as is common in connection with many otherforms of hot presses.

In order to avoid the delay incident to the moving of the movable plateof the press by means of screws and secure a greater pressure, Imake useof toggle-levers D D, joined to each other and to the base and slidingplate of the press, as shown, and I make the lower member 40f eachtoggle in the shape of a bracket with converging arms 5 6, and at themeeting ends of the said arms I attach a connectingrod 7, which extendsto a treadle 8, jointed to a bracket 9 upon the base. These parts are soconstructed that a single downward movement of the treadle by thepressure of the foot will straighten the toggles to such an extent as toforce the movable plate 0 to the limit of its upper movement, therebycompressing the holder Hand its contents.

Heretofore ithas been common in the manufacture of stays, stiffeners,&c., to place the same between the plates of the press and then bringthe plates together, but this is accompanied by considerablemanipulation, which loses a great deal of time, to avoid which I makeuse of a holder II of the character which I will now describe.

The holder H consists of a press-frame I, having cross-bars 12 12,preferably of metal, as aluminium, two perforated plates 13 13, alsopreferably of aluminium, supported on opposite sides of the cross-bars,so as to leave an intervening ventilating-space so, and two metallicsheets 10 10, secured by flexible joints or hinges to one edge of theframe I, so that each sheet can be swung away from the frame or theframe from the sheet, and to the opposite faces of the frameI apply oneor more layers of woolen fabric and a sheet 16 of fine cotton, so as toprevent the fibers of the coarser woolen fabric from being pressed intoand marring the casings of the stays.

The frame I is provided with a handle 17 opposite the edge where themetallic sheets 10 are joined to the frame, so that the frame, with itssheets, may readily be drawn out from between the plates of the press.

In operating with the holder and the press I make use of two holders HH, as illustrated in the perspective view, Fig. 2. One holder is openedand the sheets Xof boned fabric are placed between the lower plates 10and the pressframe I, and another series of sheets X are placed upon thepresser-frame I beneath the sheet 10, and then the presserframe isbrought upon the lower sheet 10 and the upper sheet 10 is brought uponthe presser-frame, and the holder thus closed is pushed in between theplates of the press, and the latter are brought together by pressingupon the treadle. After a sufficient length of time the treadle israised, the holder is drawn out by means of the handle 17 and opened,and while the boned fabrics X X are being taken out and others insertedin their places the holder H and its contents are put into the press andsubjected to heat and pressure, and by the time the contents have beenproperly pressed and dried the holder II will have been filled and isready for insertion, which then takes place after the holder H isremoved. By this means I am enabled to keep one press constantly in useinstead of being under the necessity of using two presses, asheretofore, each of which must remain idle during the time the holder isbeing discharged and replenished.

It will be seen that while the articles are being pressed the fabricwill take up the moisture, and the passage of air through the chamber xwill evaporate the moisture from the fabric.

Without limiting myself to the precise construction and arrangement ofparts shown, I claim as my invention- 1. The combination in an apparatusfor pressing stays, corset-sections, &c., of a base A, standards 3,ahollow press-plate B secured to said standards, a movable hollowpressplate 0, toggles D, one section of each toggle in the form of abracket, and a treadle connected to the bracket-section of each toggle,substantially as set forth.

2. The combination in a holder for making boned corset-sections, of fiatperforated plates supported in separated positions to form intermediateair-circulating spaces as, a layer of fabric on each of said plates, andflat flexible sheets 10, 10, connected at their edges with the plates,substantially as described.

3. The combination in the holder H, of a presser-frame consisting ofperforated plates and intermediate ribs 12, layers of fabric on oppositesides of the frame, and metallic sheets 10, 10, jointed to the frame atone edge, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN S. CROTTY.
